These pieces of furniture have gliding action. Framework is under the seat to avoid pinching problems. The blueprints include full size templetes for both a single and a bench seat, in addition to having diagrams for making the gliding hardware, though we also have a sourch for this hardware if you'd prefer to buy it (cost for one glider's hardware is about $15). A list of materials and large measured drawings are also included. Chairs measure 40”H, 33”W for the single and 45"H, 51”W for the bench.
